,s TIRE COVER.

Application filed November 2 1, 1925: Serial No. 70,455.

The present invention relates to tire covers and particularly to that type of cover in which a tire is completely enclosed to protect the tire from the action of light and 5 the weather.

Among the objects of the invention 1s a cover which is easy to apply and remove and which will present a better appearance than those now in use.

Another object is to decrease the cost of construction of such covers and at the same time produce a cover which is superior to others of similar types.

Heretofore, the best known type of tire cover which completely encloses a. tire is one having sufficient fabric to extend from one side of the tread overthe latter and around the tire to the other side of the tread, having two thicknesses of fabric over the tread,

and having a contractible and expandible ring in each educ.

This form 'of cover is diihcult to put on and take ed of a tire and especiall difcult to put on so as to present a goo appearance, because of the difficulty in lapping over the one edge while keeping the under edge properly concentric.

Another object of the present invention, therefore, is to obviate this diculty and produce a cover which shall always present a smooth, neat appearance.

Still another object 'is a cover which may be used for different makes of the same supposed size of tire.

Reference should be made to the accompanying drawing, which Fig. 1 is a cross section through a tire and cover therefor; and

Fig. Y2 is an elevation of a part of a tire 4c and cover with parts removed to show the construction of the cover.

As indicated in the drawing the cover consists of an annular 'tube of fabric 10 made up of suitable strips sewed to'vether, which tube has an annular opening along one face of the tire, the diameter of the latterannulus being intermediate the inner and outer diameters of the annular tube.

.'The'fabric edges of the opening will have reinforcing rings as indicated, the inner edge being reinforced with a ring 11 .of Substan- 'tially xed diameter and'preferably of metal rod, and the outer edge with 'an expandible 'and contractible ringl 12, preferably a con- 5a tinuous spiral spring.

in that the fabric used is less and the ring '11 is cheaper than the spring rings.

it is to be understood that the invention is In the application of the cover to a tire,l the ring 11 with the annulus 14 of fabric adjacent and secured thereto will'lie against one face of the tire l5 and the remainder of the cover will be passed through the tire and brought around over the thread, the ring 12 allowing sufficient expansion for this operation. The outer ring 12 with the attached fabric is then brought downto overlap ring 11, therebycompletely enclosing the tire in a light, water and dust-proof case.

rlihe function of ring 11 is, of course, to hold the fabric rin 14 substantially smooth against the face o -thevtire and concentric therewith during the operation of applying the cover and for this purpose it should be relatively stiff. A certain degree of den` ibility is, however, permissible.

In coverin dierent makes of the supposed same size of tire, the onlyT dierence will be in the overlap of the edges ofthe opening.

rlihe present form of cover is not only superior to the known cover but is cheaper Further, the ring 11 and fabric annulus 14 position the cover during its application and it is therefore easy to apply properly, with the rings 11 and 12 upon the rearward face of the tire, presenting to ordinary view the smooth fabric on the side opposite the rings.

Having now described the invention and the preferred form of embodiment thereof,

aa to be limited not to the specific details herein set forth but only'by the scope of the claims which follow.

1. A tire cover consisting of an annular et sheet of fabric, the edges of which are adapted to overlap at one side ofthe tire between the tread and beadl portions and means for maintaining the one edge concentricwith the tire during overlapplng of the me other edge, c

.2.. A tire cover-'consisting of an annular sheet of fabric, the edges of which are adapted to overlap at one side of the tire between the tread and bead portions and relea silient means for maintaining the edges in. engagement when said cover encloses a tire.

3. Atire cover consisting of an annular sheet of fabric, having fixedto one edge a reinforcing ring of substantially fixed diameter intermediate the rim and treaddiame-l ters of the tire, the edges of said sheet adapted to overlap at one sidel of the tire, and an extensible and contractible reinforcing rin secured to the other edge of said sheet an adapted to hold said second named edge in overlapping relation tov said first named edge. l l

4;. In a tire cover, a substantially iat annulus of fabric having in its outer edge a fixed diameter ring, said annulus' and ring adapted to lie against one side wallof a tire with the ring inside of the line of tread, additional' fabric secured to said annulns adapted to extend around the tire and voverlap said fixed diameter ring, and -an exj audible and contractible ring. in the over-l Y appingedge of said fabric.

5. A tire cover consisting of an vannular sheet of fabric made up of' a plurality of fabricl strips one 'of which is a substantially flat ring or sufficient width to extend from the la'tV inner surface of the tire to near the tread'thereof and has its outer edge provided with a comparatively stii ringz other strips sewed together and to rsaid fabric ring at its inner e ge to -cover the rest of sthe tire and lap over the outer edge of said first ring', the lapping edge being vprovided with a ring of extensible material.
